MARTIN E. BEIGE-1AM, OF PHILADELPEIA, PENNSYLVANIA.

OILING DEVICE.

To all whom it may concern:

Be it known that I, MARTIN E. BRIGHAM, a citizen of the United States, and resident of the city and county of Philadelphia, State of Pennsylvania, have invented an Improve ment in Oiling Devices, of which the following is a specification.

My invention has reference to oiling de vices and consists of certain improvements which are fully set forth in the following specification and shown in the accompanying drawings which form a part thereof.

My invent-ion has reference to that class of oiling devices adapted to engines and ma.- chinery where there are a large number of parts which require to be individually oiled, whether the said supply of oil is required to be the same or in different quantity to the respective parts. My improvement is particularly useful in automobiles where the machinery is out of close observation and where the duty on the engine is especially hard and necessitating lubrication which must be amply suiiicient to meet the utmostrequirements without waste.

The object of my invention is to provide suitable automatic means for supplying lubrication to a plurality of independent portions of one or more machines from a common source of oil supply; and moreover to insure therequisite amount of oil being delivered to each of the parts to be lubricated without regard to the amount ofoil delivered to any of the other parts.

lily invention has a further object in the economical distribution of the oil, whereby all waste is eliminated and only the exact amount necessary is supplied to the parts to be lubricated for a given amount of work to be done.

My invention consists of certain features of construction by which-the above objects are carried out, the said construction being fully described hereinafter and more particularly defined in the claims. These improvements wil be betterunderstood by refcrence to the drawings, in which:

Figure l is a rear elevation of an oiling apparatus embodying my-invention; Fig. 2 is a front elevation of the-same with the oil tank removed; Fig. 3 is a sectional elevation of the distributing device; Fig. 4 is a cross section thereof; Fig. 5 is a perspective view of the eccentric yoke for operating the Specification of Letters Patent.

pumps; and Fig. 6 is an enlarged sectional elevation of one of the sight feeding devices for controlling the relative amount of oil distributed into each distributing pipe.

2 is a reservoir for the lubricant and may be of any character desired, 3 is a distributing case into which the oil is pumped under pressure by pumps 4, the said pumps be ing provided with suction pipes 5 which connect with the oil supply pipe 5 through a cross fittin 5 The pump cylinders 4 are each provided at their outer ends with check valves 6 which may be of any suitable character, but preferably of the construction shown in Fig. 8 and screwed into the ends of the pump cylinders. These check valves 6 have the valve pieces 6 preferably spring pressed upon their seats by coil springs 6". Each of the pump cylinders is provided with a plunger 19, said plunger being made tubular and having a valve seat 23 upon which a check valve 2 seats itself under the action of a spring 22, said parts being located within the plungers, as shown in Fig. The plungers are respectively secured to each side of a yoke 18 within thecase 3 which is reciprocated by an eccentric 17 formed on a rotating disk 12 arranged within the case 3 andjournaled at 13 in hearings in the body of the case and the cover plate 3, as shown in Fig. l.- This disk 12 is provided with teeth 14 which are driven by a worm 15, rotated by a shaft 16, and by which the disk is positively rotated at a moderate speed and caused to operate the pumps 4:. The shaft may be rotated by any means desired, but-is usually connected with some part of the operating machinery to be lubricated. The particular manner of rotating the disk is immaterial. The disk 12 is provided with one or more apertures 20, and on one side, in circular a'linement with said apertures the disk is turned true, to form seats 21. These annular seat portions work against the inner face of the case 3, through which there are a plurality of distributing ports '26, said ports arranged in circular 1 form so that the apertures 20 in the disk-are brought successively into alinement with the said distributing ports 26. The disk 12is pressed toward the distributing ports by means of a spring 27, which is put under 'tension by a screw: or other-suitable adjusti11 device 28.

Each of the distributinc ports 26 connects with a separate distributlng pipe 7 through a sight feed mechanism 29, which may be of any ordinary construction and is preferably provided with the adjusting valve 30. In

Fig. 2, fourteen of these distributing pipes and sight feeds are shown arranged in two concentric circular rows, and of course it will be understood that more or less of such distributing outlets may ,be employed, as desired. By employing sight feeds 29, it is evident that as the oil is delivered to all of thadistributing pipes under the same pressure, the amount of oil which actually flows into each distributing pipe may be regulated under sight adjustment by means of the ad just-ingzvalves 30. Where the oil is not pe r mitte'dto fall by gravity but is circulated 111 the pipes 7'under forced pressure, the slght feedswould not berequired, except to know that oil was flowing; and in this case the ad justing valves;30* may be employed without the sight portions, as the oil would flow through the distributing pipes 7 (under the pressure existlng. within the case) whenever one ofthe apertures 20 comes in front of the forced through this safety valve enters a bypass 34whichconnects with the cross fitting 5 and re-circulates to the pumps 4'. In this manner, no excessive pressure can be put upon the oil within the case 3, and whatever, pressure is intended, 1s definltely predetermined by the tension of the sprlng 33.

This tension'may be adjusted byforming the part 35 of the safety Valve adjustable and thereby putting the spring under more or less tension, as desired.

The ,casing 3 is, provided with an air chamber 36, preferably opening from the cap above the worm I5, and a pressure gage 37 may be attached to the air chamber 36 and.

be located ina suitable position for observatiori. As the air is sealed above the oil within the air chamber 36, the elasticity of the air is always available for causing a steady and elastic flow of the non-elastic oil, and

hence there is very little danger of leakage from hydrostatic pressure; As before stated, should the pressuretend to increase above the predeterminad amount by failure of'the oil to pass out through the distributing pipes with sufficient soeed, the pumps will re-circulate the oil within the case through the by-pass '84: and safety valve 31.

. ters Patent, is: Z

If, from any cause, the apparatus for rotating the disk 12 should become deranged,

it is evident that there would be nor'delivery of oil through the distributing pipes, except :in case that one of the apertures 20 in the disk should happen tobe over one of the idistributing ports 26;

possible contingency, I provide an adjusting 13, which, upon being screwed up, wil1 push the disk away from the case and allow the oil to enter the various distributing ports 26 directly. In this manner, the oiling devices may be operated similarto any ordinary static distributer' with sight. feeds;

To overcome this ,screw 38 in. the end of one of thebearings;

This adjustment may be maintained by means of a lock nut 39. V v

I prefer to locate the oilcreservoir at a higher elevation 'thanthe'case 33- so tha tth'e Oll feeds to the pumps'by gravity, said construction being indicated in Fig. l, but I do not restrict myself't o thisarrangen ent as, broadly considered, it is immaterial how the oil reaches the piimps,:whether by suction or gravity. 1

While, for convenience andcompactness,

I have arranged the pumps within'the case,

it is evident that the operation would be the same if the pumps were arranged otherwise,

andmoreover, while I employ two pumps, it s evident that cneof these'may be dispensed with, if so 'desiredjand I therefore do not limit myself to such details. Theadvantage ofusing twopumpsis that, two single acting pumpsaccomplish the same resultasa double acting pump, and moreover maintaina constant circulation oftheoil.

Ihave shownmy invention in the form in which I have used it in commercial practice, V and while the construction shown 1s com-.

mercially satisfactory and practical, I nevertheless do not limit myself tothe details and they may be modified without departing from the invention defined in the claims.
